Android - Proguard avec httpcore et httpmime sous Android Studio et Gradle

Je développe une application avec Android Studio 1.0.2 et Gradle 1.0.0 à l'aide des bibliothèques Apache httpmime et httpcore pour des entités en plusieurs parties. Voici mon build.gradle:

apply plugin: 'com.Android.application'

Android {
    compileSdkVersion 21
    buildToolsVersion "21.1.1"

    // Something wrong with the http* libs
    packagingOptions {
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/DEPENDENCIES.txt'
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/NOTICE.txt'
        exclude 'META-INF/NOTICE'
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/notice.txt'
        exclude 'META-INF/license.txt'
        exclude 'META-INF/dependencies.txt'
        exclude 'META-INF/LGPL2.1'
    }

    defaultConfig {
        // ...
    }

    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-Android.txt'), 'proguard-rules.pro'
        }
    }

}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile "com.Android.support:support-v4:21.0.2"
    compile 'org.Apache.httpcomponents:httpcore:4.3.2'
    compile 'org.Apache.httpcomponents:httpmime:4.3.5'
    compile 'net.hockeyapp.Android:HockeySDK:3.5.0'
}

L'application elle-même et la version "normale" des APK fonctionnent bien, mais lorsque j'essaie d'utiliser ProGuard, le message d'erreur suivant s'affiche:

En fonction des liens indiqués dans le message d'erreur concernant les définitions de classe en double et les classes de bibliothèque en fonction des classes de programme, je devrais utiliser quelque chose comme -injars ... ou -libraryjars ... dans mon proguard-rules.pro. Mais comme j'utilise les bibliothèques distantes et non les fichiers .jar, je ne sais pas comment utiliser ces options de proguard.

J'ai donc cherché sur Google une solution à mon problème et j'ai trouvé plusieurs possibilités:

  • J'ai téléchargé les fichiers jar, les ai ajoutés à mon dossier \app\libs et les options -libraryjar et/ou -injar pour les deux fichiers, mais aucune combinaison ne fonctionnerait. Soit les fichiers étaient introuvables ou ne pouvaient pas être lus, soit un message d'erreur les bibliothèques seraient traitées deux fois.

  • J'ai également essayé diverses combinaisons de -keep class org.Apache.**, -keep interface org.Apache.**, -keep public class org.Apache.** {*;}, -keepnames class org.Apache.** {*;} avec ou sans le {*;}, mais aucune d'entre elles ne fonctionne.

  • J'ai également essayé l'option -dontwarn org.Apache.** ou -dontwarn org.Apache.http.** qui ne me donne aucune erreur lors de la création de l'APK, mais lorsque j'essaie d'établir une connexion Internet à l'aide de http * libs dans l'application, l'application se bloque avec quelque chose comme une exception NoSuchMethodException.

Ma question est donc la suivante: existe-t-il un moyen d’utiliser les bibliothèques distantes et proguard? Ou est-ce au moins possible en incluant les fichiers .jars dans mon dossier\libs?

Merci beaucoup

Eh bien, j'utilise comme ça 

-dontwarn org.Apache.commons.**
-keep class org.Apache.http.** { *; }
-dontwarn org.Apache.http.**

Aussi je suis en train de compiler en utilisant jar dans mon dossier libs

compile files('libs/httpmime-4.3.5.jar')
compile files('libs/httpclient-4.3.5.jar')
compile files('libs/httpclient-cache-4.3.5.jar')
compile files('libs/httpcore-4.3.2.jar')

au lieu d'utiliser de maven

Essaye ça 

-dontwarn org.Apache.commons.**
-keep class org.Apache.http.** { *; }
-dontwarn org.Apache.http.**
-dontwarn com.squareup.okhttp.**
-dontwarn okio.**
-dontwarn retrofit2.**
-keep class retrofit2.** { *; }
